This paper examines the benefits of element interaction effects on cold-formed ferritic stainless steel compressed sections on the basis of carefully validated finite element models.
Comparisons with the loads achieved in the FE models have shown that the proposed effective width equations allowing for the benefits of element interaction improve capacity predictions making design more cost-effective.
In addition, the full cross-section slenderness allowing for element interaction, which is utilised in the direct strength method (DSM) and the continuous strength method (CSM) has been considered as the slenderness parameter in a new classification framework.
Hence, for non-slender cross-sections, the codified design stress is limited to the 0.2% proof stress without considering the pronounced strain hardening exhibited by stainless steels, while for slender cross-sections, the effective width method is employed without considering the beneficial effect of element interaction.
The critical local buckling strengths were determined from the measured out-of-plane deflections and surface strains corresponding to the plate elements, which were further compared with the theoretical and analytical values taking into account element interaction and material non-linearity.
Initially, an equivalent simplified web local buckling model was proposed, in which the cross-section plate element interaction of the flanges and the lips on the web were modeled by rotational springs and the loaded edges were assumed to be uniformly compressed and to be simply supported or fixed.

We extend its traditional formulation to the case of multi-dimensional signals in order to capture group interactions, and not only element interactions.
The Taq RPo structure also recapitulates the σ2/−10 element interactions seen in high-resolution (2.1 Å) structures of Taq σ 2 A complexes with ss −10 element DNA (Feklistov and Darst, 2011).
Receptor-attached phosphates destabilize both the polar core (Vishnivetskiy et al., 1999) and three-element interaction (Vishnivetskiy et al., 2000), enabling transition into high-affinity receptor-binding state.
The other clasp is the three-element interaction of β-strand I and α-helix in the N-domain, and β-strand XX in the C-tail (Hirsch et al., 1999) (Figs. 1 and 2A).
